comprises a frame which iincludes vertically 1 disposed standards 1.1which 'may be ar-'- ,f v ranged in pairs asshown in Figure 1' of the I edrawin'gsandconnected by cross beams l2 y and 13, the latter beingrelatively short 1651 f beams for-{supporting the feed belt rollers tobehereinafter described. a r I y it .*Mounted in bearingstandards .14 at-0pposite ends of the machine are'shafts l5 and which travels an endlesscarrier. 4 if t The carrier just mentioned is formed of, individual'carrier'blocks 18 from the oppo- 165. These shaftss'upportrollers'lTaround site ends of, which extendtrunnions 19,'the'latterbeingconnected with chains 2'0.- The 7 3 chainsfl20 travelaroundspreckets 21-atep pesite ends of the machine and the upperfflights of the 'chainstravel overa -bea'ring i hplate'22. This bearingplate. iszprovidedfl s with a centrally arranged rib 23 which ex:

tends longitudinally of the plateand the, blocks l8 areprovided withcentrally 10- ca'ted recesses 24 which take over the rib I 23 so as t0guidethe blocks and cause them to travel'in a direct line over thebearing 8i "Plate. I

The shaft 16 hasmcunted thereon a gear 25 and mounted for freeretatienupon-this shaft is -a pulley 26 which is locked tothe shaft by meansof aclutch 27 which is con- W trolled by a lever 28; The shaft-16 maythus'be engaged with and disengaged from I V a suitable source ofv powerfor controlling I itsrotation. 5 a L The shaft 1'5 ismounted in anadjustable I bearing29, so that the 'chains 20 may be ad 2 a justed forproper operati o'n. i J y s 3 Mounted in bearings30 above'the bearingplate 22 are shafts iiliand 32, the first mene tion'ed shafts havingsecured thereto beveled gears 33 which are driven by beveled gears 34mounted upon stub shafts 35. These last m'entioned shafts are mounted insuitable mounted upon the. shaft 16.

These last mentioned. gearsare engaged and driven. by the gear'25 and a gear 38, both The shafts 31and 32 carry vertically "disl posed rollers 39 around which travel feed.belts40. These belts preferably consistof an inner leather belt 41having an outer fac ing of rubber 42. By reference to Figured.

of the drawings it will be seen that the belts are horizontally spaced,the space-which is indicated at 43 being directly above the center of'thG'fCZLI-I'iGD blocks: and; being adapted to receive theglass'or'other panel v ltobe edged. In order that'properpressure may bebrought upon opposite sidev faces of the panel the inner fiightsof thebelts 42 are reinforced by rollers &5 which are spaced along and bearupon the inner faces of these belts.

Positioned above the machine is a rail' lti,

which as shown: in Figure 6 of the drawings,- is preferably an IbeamrThis rail supports a carriage 47 which includes rollers 48', the lattertravelling along the beam. Depending from the carriage 47 is a clampwhich comprises jaws 49'which are pivotally mounted as at 50 forclampingengagementi upon opposite facesofthe "panel 44. The

jawsare connected by means of a. rod '51 whichsupports springs 52Jwhosefunction is'to yieldingly position.

hold the jaws in clamping. The carrler blocks 18 have removably 'secured thereto edging elements 53. r These. elements may consist-ofblocks of, rough em-' ery, carborundum, smooth stone, cork, woodorpumice stone. The edging elements have a dove-tailed engagementwith theblocks. 18

as shown at 54: and are further. held in po 1 sition by means of screws55. These screws pass through openings 56 provided'in'the edgingelements and engage threaded sockets 57 in the carrier blocks 1 8; Theedging elements are thus 1 .removably secured in place so that themachine may be used either for grinding, smoothing orpolishing'by inserting the proper type of edging element forthe work intended. It isobvious that if desired threemachines may be used, the first beingarranged for grinding, the second for smoothing, and" the third forpolishing.

j Located at each end of the machine is a table 58. These tables areprovided with a covering 59 of leather or other'suitable material andthe glass panel is slid along this table between the feed belts 40am isgripped and carried by these belts through themachine while the edgingelements are acting upon-the loweredge ofthe panel. The clamps 49, oneof which is engaged near each endoffthe panel, actto positively 'gripand hold the panel a direct vertical position and causes it to'travel'ina direct horizontal line so as to provide. a proper edgeat the bottom ofthe panel. 'Theedging elements 54 are provided with grooves 60 withinwhich the bottom edge of theglass rests so that this edge .ofthe-glassis properly held in-pos'ition as 1 theedging elements 'travel ina directline due to the engagement.

of, the carrier blocks withthe rib V In order to properlyfregulate thehorizontal position, of the abrasive element, the

bearing plate 22 is vertically adjustable. -,For this purpose,-the plate22 is secured to beams 61 which extend transversely of-the frame and arespaced longitudinally there' 0ft These beams havef their'oppositetendsthreadedly engaged by vertically E disposed rods 7 62 whoselower-ends are mounted in.

bearing blocks 63. Secured to the rods 62,

means of the hand wheels 68, the-threaded shafts 62 may be rotated toadjust the position of the beams-.61 andithus regulate the position ofthe bearing: plateso that the.

latter may be adjusted to the proper width of the glass :panel and themeasurementsof the latterwill be accurate when theedging operation .iscompleted. V i "Guard rails69 are securedialong opposite edges of thebearing plate 22 and extend inwardly over the edges of the edging. Tele.
